Unit 2 is typically a five-week unit taught from October to December.
Mathematics is the study of patterns and relationships. In this unit, students analyze the characteristics and relationships of geometric shapes and structures. They examine properties of basic plane figures and explore the properties of three-dimensional figures by applying their knowledge of two-dimensional figures.
Geometry deals with the properties of well-defined sets of points. In Grade 4, students compared and classified figures according to these properties as they developed geometric vocabulary and symbolic representation. In this unit, students use tools such as computer software, compasses, rulers, and protractors to draw geometric figures. They extend their knowledge of vocabulary and concepts related to circles. Many Grade 5 students are able to move developmentally from analysis of plane figures (e.g., A rectangle has four sides and four right angles.), to informal deduction (e.g., Since a square has four sides and four right angles, then a square must be a rectangle).
The concepts of solid geometry help us describe and represent our three-dimensional world. Students begin identifying solids in kindergarten and each year they extend and refine their understanding. In Grade 5, students use what they have learned about the properties of solid figures and the relationships of plane to solid figures to compare and classify solid shapes.
The understandings that the students develop in this unit provide a foundation for their work in Math A on combining and dividing geometric shapes, making two- and three-dimensional models, and developing and using formulas for perimeter and area of polygons.
